With the Omega Speedmaster Chronoscope, reference 329.30.43.51.03.001, the whole story is already in the name. Collectors simply call it the Chronoscope, some also know it as the Snail Dial Speedy or the Three-Scale Speedmaster — three nicknames for one and the same 43mm steel watch that brought classic Speedmaster DNA together with an almost-forgotten complication in 2021. Inside beats the Caliber 9908, a manual-winding Co-Axial chronograph with Master Chronometer certification, one that extends the Speedmaster line with a legibility idea all its own.
## The Blue Snail at the Center
The Snail Dial nickname isn't accidental. The opaline blue dial carries concentric scales that spiral inward like a snail shell — tachymeter, telemeter and pulsometer aren't confined to the bezel as usual, but reach into the dial design itself. Three measuring functions on a 43mm surface, without the watch ever feeling cluttered. That density is exactly what makes this piece interesting from a valuation standpoint, since the condition and legibility of those fine spiral lines weigh heavily on the price it can command.
## The Bezel Carries the Second Signature
The black aluminum bezel with its tachymeter scale looks classic at first glance, but it adds a fourth reference layer to the dial's three scales. Combined with the steel case and the Caliber 9908, this Speedmaster positions itself clearly between vintage homage and modern manufacture technology. For market valuation, one thing matters most with this reference: box completeness, since Chronoscope models are still relatively young on the secondary market and the data pool is correspondingly thin.
Brand profile: Omega
Omega is the second most counterfeited Swiss watch brand. The Speedmaster and Seamaster are especially targeted. Pay close attention to movement details (Co-Axial) and dial textures.
- Speedmaster: The chronograph reset hand must snap back precisely to 12 o'clock — fakes stop 1–3 seconds off or wobble
- Speedmaster (Hesalite): The Omega logo is micro-laser-etched on the UNDERSIDE of the Hesalite crystal — only visible at a specific angle and in the right light — fakes omit it or place it incorrectly
- Seamaster: The wave-pattern dial must be ENGRAVED (tactile relief) — printed/flat wave lines = fake
- DON (Dot Over Ninety): small dot ABOVE the '90' on the Speedmaster tachymeter bezel — position/size often wrong on fakes
Serial number format: Omega serial number: 8-digit number on the caseback or between the lugs (on older models). Since ~2018 engraved on the caseback at 6 o'clock. Format: purely numeric. Verifiable on the Omega website with an extract from the archive.
